Hi:
I have no experience with vents placed that way, but a couple of thoughts
leap to mind.  Will there be dust raised (pun intended) by the air coming up
from the floor, given that dirt/dust will inevitably get into the ducts from
the floor?  Will it be possible to push the cold air up enough to displace
warm air at the ceiling without the air movement being fairly strong and
disruptive to visitors?  Are you going to remove the ceiling ducting?  If
not, why not reuse it?  If you are, is there any cost-saving by leaving it
in place and reusing it?
I think I would also want to have some assurance that there will be adequate
diffusers for the air to ensure that there would not be cold/hot spots.
Those are relatively easy in the ceiling, perhaps more complex in the floor.
